Preventing UI_HEADERS_DIR from being added to include path

[tbscope]

Sorry for asking stupid questions, but I don't understand your problem.
Are you trying to build separate targets? Why do you want to copy headers?

Edit: well, I do understand what your problem is, but not why.

As i said, i have two types of libraries, core and gui. Let's say core library (libtbs) has a signal class resides in "signal.h" and "signal.cpp" both are in "source/libtbs" directory. To use signal class from within signal.cpp or any other file within core library i'm including it like #include "signal.h"

That's ok. But when i need to use signal class from one of the unit tests or from a gui library, #include "signal.h" will not work. Since they are not in the same directory. Adding "source/libtbs" to include path (-I../libtbs) will not work either as "signal.h" from libtbs and "signal.h" of POSIX will be included in place of each other... So, the headers of libtbs must be copied to "builddir/include/tbs" and "builddir/include" must be added to include path then users of core library can include and use "signal.h" as #include <tbs/signal.h>

Setting UI_HEADERS_DIR to builddir/include/tbs also enables -I builddir/include/tbs causing "signal.h" of core library to be included in place of POSIX one.

Wouldn't it be easier to just rename your signal.h to tbs_signal.h ? Then you have no collisions to worry about and can just use the paths as normal without copying header files around.

[extronus]

It is. However this will move signal.h from it's own _namespace_ to global one. ( #include <tbs/signal.h> | #include <tbs_signal.h> ) breaking source consistency with previous versions etc... Isn't it correct way to shape the build system for project instead of shaping the project for build system?

I've managed to solve the problem by overriding uic.

The key point is disabling the uic by adding "CONFIG -= uic" then using a custom compiler. I'm posting both full configuration file and another that uses it.

pri file.
