[CMake] debugging CMAKE_PREFIX_PATH

[Patrick Welche]

I am trying to build a package which has in its CMakeLists.txt:

set(CMAKE_PREFIX_PATH "${QT_PREFIX}/lib/cmake")
set(CMAKE_INCLUDE_CURRENT_DIR ON)
find_package(Qt5Core ${QT_MIN_VERSION} REQUIRED)

(It may be that QT_PREFIX is not set?)

I build with -DCMAKE_PREFIX_PATH set, and in CMakeCache.txt, I see:

//No help, variable specified on the command line.
CMAKE_PREFIX_PATH:PATH=/usr/pkg/qt5 

//The directory containing a CMake configuration file for Qt5Core.
Qt5Core_DIR:PATH=Qt5Core_DIR-NOTFOUND

# ls /usr/pkg/qt5/lib/cmake/Qt5Core/Qt5CoreConfig.cmake
/usr/pkg/qt5/lib/cmake/Qt5Core/Qt5CoreConfig.cmake

so AFAICT, Qt5CoreConfig.cmake should be found.

What am I missing?

Cheers,

Patrick
