Description
I'm building Qt 6 with cmake (not using the configure script) on Ubuntu 20.04 x86_64. When I try to enable `gtk3` support with option `-DFEATURE_gtk3=ON` then cmake fails with error:
-- Checking for module 'gtk+-3.0 >= 3.6' -- Package 'bzip2', required by 'freetype2', not found CMake Error at qtbase/cmake/QtFeature.cmake:207 (message): Feature "gtk3": Forcing to "ON" breaks its condition. Call Stack (most recent call first): qtbase/cmake/QtFeature.cmake:288 (qt_feature_set_value) qtbase/cmake/QtFeature.cmake:474 (qt_evaluate_feature) qtbase/cmake/QtModuleHelpers.cmake:397 (qt_feature_module_end) qtbase/src/widgets/CMakeLists.txt:7 (qt_internal_add_module)
I have freetype2 and bzip2 installed (as shared libraries, with a cmake-based build) in `PREFIX`, with package configurations in:
PREFIX/lib/cmake/bzip2/ PREFIX/lib/pkgconfig/bzip2.pc PREFIX/lib/cmake/freetype PREFIX/lib/pkgconfig/freetype2.pc
The path to PREFIX is passed to cmake via
-DCMAKE_PREFIX_PATH="PREFIX;PREFIX/lib/cmake"
This generally works with Qt to find our other dependencies (like libtiff, zlib, png, and many others). Also, bzip2 is found in other cmake builds like OpenCV or BioImageConvert, so I assume that the installation is correct.
It seems to fail only for bzip2 as a dependency of freetype2 for Qt?
