[CMake] debugging CMAKE_PREFIX_PATH

[Patrick Welche]

I think I am confused by the following:

1) CMAKE_PREFIX_PATH;

Problematic (scribus) CMakeLists.txt:   

   set(CMAKE_PREFIX_PATH "${QT_PREFIX}/lib/cmake")

CMakeCache.txt:

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

So the problem was that CMakeLists.txt overwrote the command line.
Removing the set() line made things work

2) CMAKE_MODULE_PATH

CMakeLists.txt (with extras to debug):

  set (CMAKE_MODULE_PATH "/usr/obj/pkgsrc/print/scribus5/work.x86_64/.buildlink/cmake-Modules" "one" "two" "/usr/obj/pkgsrc/print/scribus5/work.x86_64/.buildlink/cmake-Modules" "${CMAKE_SOURCE_DIR}/cmake/modules")
  set(testpath ${CMAKE_MODULE_PATH} CACHE PATH "testing path")

CMakeCache.txt:

  //No help, variable specified on the command line.
  CMAKE_MODULE_PATH:PATH=/usr/obj/pkgsrc/print/scribus5/work.x86_64/.buildlink/cmake-Modules

  //testing path
  testpath:PATH=/usr/obj/pkgsrc/print/scribus5/work.x86_64/.buildlink/cmake-Modules;one;two;/usr/obj/pkgsrc/print/scribus5/work.x86_64/.buildlink/cmake-Modules;/usr/obj/pkgsrc/print/scribus5/work.x86_64/scribus-1.5.3/cmake/modules

So here, it seems the command line overwrites CMakeLists.txt ?!

Cheers,
