Hello,
on a really weird configured system (but I can't change it), there is a
pkg-config file which I want to find with cmake:
set(ENV{PKG_CONFIG_PATH} "$ENV{PKG_CONFIG_PATH}:$ENV{PETSC_DIR}/lib/pkgconfig")
set(CMAKE_PREFIX_PATH "$ENV{PETSC_DIR}/lib/pkgconfig")
find_package(PkgConfig REQUIRED)
pkg_check_modules(PETSC REQUIRED craypetsc_real)

pkg-config also finds it:

CMakeError.log does not exist, CMakeOutput.log I have attached.
Hi Florian:
What happens if you set PKG_CONFIG_PATH outside cmake rather than inside?
e.g.,
env PKG_CONFIG_PATH=$PETSC_DIR/lib/pkgconfig cmake ....
with both
set(ENV{PKG_CONFIG_PATH} "$ENV{PKG_CONFIG_PATH}:$ENV{PETSC_DIR}/lib/pkgconfig")
set(CMAKE_PREFIX_PATH "$ENV{PETSC_DIR}/lib/pkgconfig")
commented out inside your CMakeList.txt file?
That method has always worked for me. And if it works for you, then I would
think attempting to set the enviroment variable PKG_CONFIG_PATH inside
your CMakeLists.txt file with just
set(ENV{PKG_CONFIG_PATH} "$ENV{PKG_CONFIG_PATH}:$ENV{PETSC_DIR}/lib/pkgconfig")
(setting CMAKE_PREFIX_PATH should not be required) should just work, but it is
always possible (although I haven't checked documentation to see) there is
some incorrect syntax in that line so I would also use message to print
out the PKG_CONFIG_PATH environment variable to see what you have actually
set it to within CMake.
