My machine use Ubuntu OS.
I built Qt 5.5.1 manually against static linking. Configuring the built, specified a path to install to:
$ ./configure -static -prefix /home/myname/qt_src/installed/
Then I moved the built stuff to another Ubuntu machine and tried call qmake from a shell:
$ qmake CONFIG+=release CONFIG-=debug /home/othername/project/q_panorama.pro -r -spec linux-g++
But I stucked with error
Could not find qmake configuration file linux-g++
Trying to fix it, I discovered that qmake's QTDIR (is it?) is incorrect:
$ qmake -v
QMake version 3.0
Using Qt version 5.5.1 in /home/myname/qt_src/installed/
Okay. Try to change special var with qmake -set option (here consider only one of vars - QT_INSTALL_PREFIX, - for simplicity). First, check it's consistency:
$ qmake -query QT_INSTALL_PREFIX
/home/myname/qt_src/installed/
Perform:
$ qmake -set QT_INSTALL_PREFIX "/home/othername/qt_static/"
Check again:
$ qmake -query QT_INSTALL_PREFIX
/home/myname/qt_src/installed/
Why the variable does not modify?
How can I make Manually Built static version of Qt work? Please, help.
Did not find the way to resolve the issue, and thus decided to act with brute force:
Created a user othername in my machine;
Run full build cycle for the path desired (under the user created).
Copied the built stuff to the target machine
PROFIT.

I am currently using Ubuntu 14.04 LTS.
How can I statically build Qt 4.8.5 -
https://download.qt.io/archive/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.tar.gz
such that when I cmake OpenCV 2.4.13 -
https://github.com/opencv/opencv/archive/2.4.13.zip
it correctly identifies the location of Qt4 ?
When I cmake OpenCV after I have installed Qt4 in /usr/local/qt4-static/, the find_package(Qt4 REQUIRED QtCore QtGui QtTest) function call within opencv-2.4.13/cmake/OpenCVFindLibsGUI.cmake fails because it cannot find qmake. Also, upon running the qmake -query in the terminal, Ubuntu says that qmake is not installed, when it clearly in /usr/local/qt4-static/.
How should I go about this so OpenCV cmake correctly recognizes Qt4 ?
Build Qt
Extract the source-code and run ./configure && make and then sudo make install. It should create all necessary configuration to run qmake in any folder (system-wide).
Additional: create a symlink/export (use only if make install did not work for you)
You need to promote qmake to $PATH or create a symlink, but this is usually done when you run sudo make install after make in the Qt source-folder.
root:/home# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:
Symlink (permanently)
ln -s /path/to/qmake /usr/sbin/qmake
or
export (temporary)
export PATH=$PATH:/folder/of/qmake
Afterwards qmake -v is working whereever you are
root:/tmp qmake -v
QMake version 3.1
Using Qt version 5.10.1 in /usr/local/Qt-5.10.1/lib
If your project still cannot determine the location of Qt, read the pro/pri/cmake file to understand how it looks for the path.
I have the following setup (using qt 5.6.1-1):
qtbase/bin
...
qtbase/mkspecs
...
qtdeclarative/mkspecs
When trying to build qtquickcontrols I get the following error:
qmake
make
Some of the required modules (qtHaveModule(quick)) are not available.
Skipped.
I think it's because qmake is only looking for .pri files in qtbase/mkspecs. Is there an environment variable to set the mkspecs
search path?
I tried setting QMAKESPEC, QT_PLUGIN_PATH and INCLUDEPATH, but couldn't get past the error message.

If you have a properly set up Qt installation, it won't be a problem. Make sure that:
You've compiled all the modules.
You haven't moved your Qt build: it has hardcoded paths and can't be moved once built.
You should also prefer to build Qt in its own build folder, if you aren't doing it already.
I'm trying to build Qwt to a custom location. The obvious thing to try is a PREFIX option, but it had no effect and the make install still failed:
$ qmake qwt.pro PREFIX='/my/path'
$ make
$ make install
mkdir: cannot create directory `/usr/local/qwt-5.2.3': Permission denied
There seem to be numerous other questions and answers to this question, which also have no effect and fail:
How to change qmake PREFIX location: qmake -set prefix '/my/path'
How can the install path be set for a qt project: make; INSTALL_ROOT=/my/path; make install
Any other suggestions?
QMake version 2.01a
Using Qt version 4.5.3 in /opt/Qt4/4.5.2/qtsdk-2009.04/qt/lib
RHEL 5.10
Try to edit the qwtconfig.pri file in the source directory, it has the installation path hardcoded for different platforms, as well as many other options you might want to change.
qmake: could not find a Qt installation of ''
This thread was not of any help to me. qmake: could not find a Qt installation of ''.
How can I get qmake to recognize where the Qt folder is?
Right now it is installed in /opt/Qt5.1.0.
Have you installed the qt5-default ? You need to do this in addition to running the Qt supplier .run file.
sudo apt-get install qt5-default
This message shown by qtchooser app.
To setup it properly, you should make conf files in /etc/xdg/qtchooser/
for example:
$ ls -1 /etc/xdg/qtchooser/
default.conf
qt-4.8.5.conf
qt-5.1.0.conf
each file has two lines: path to bin, path to lib:
$ cat /etc/xdg/qtchooser/default.conf
/opt/Qt/4.8.5/bin
/opt/Qt/4.8.5/lib
additional info: man qtchooser
The solution for me on this problem was to specify the QT version, as this message was being generated by /usr/bin/qtchooser
So in my case, it was QT4 I was trying to use, and running:
qmake
generated the error (could not find a Qt installation of '')
qmake -qt=qt4
fixed that error though. In my case, it was a Ruby Gem trying to compile with qmake, so I couldn't get it to pass in that extra command line argument, so I instead added this to my profile
export QT_SELECT=qt4
And now QT4 runs just fine on my Ubuntu system.
For me the symlink to default.conf was missing in /usr/share/qtchooser. It wasn't enough to put it into /etc/xdg/qtchooser.
I've try few things but I still have this error when trying to cmake for blackfin:
CMake Error at CMakeLists.txt:116 (message):
Fatal error: QT (version >= 4.5.0) required. Cmake tries to detect QT4 by
searching for 'qmake' in your PATH.If you have QT4 installed, make sure
qmake is found in your PATH. If you compiled QT4 yourself make sure your
new qmake ist found _first_ in your PATH.
I'm trying to compile the source of musescore 0.9.5 to keep it compatible with the existing version of QT in uClinux options
What I did is to compile the uClinux kernel with QT lib so I can have the suitable embedded QT.
then I modified the Makefile of musescore to build with uclinux compilers. I've try different things so I show here the latest trial:
bfin:

mkdir install; \

You need to put qmake in your $PATH. If you prefer to use QT_QMAKE_EXECUTABLE it has to point to the actual qmake binary and not the directory.
That being said, MuseScore 0.9.5 is a very very old version of MuseScore, the current version is 1.1 and 1.2 is coming soon. Check http://musescore.org for more information about MuseScore and don't hesitate to contact the developers on #musescore on freenode.net or on the developer mailing list at http://musescore.org/mailing-list
