            Bug ID: 103093
           Summary: CMake Error at cmake/modules/FindLIBOPENJPEG.cmake:41
                    (check_cxx_source_compiles)
           Product: poppler
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: poppler-bugs at lists.freedesktop.org
          Reporter: jwilk at jwilk.net

In some setups (non-GCC compiler + no openjpeg2 + openjpeg installed, but
openjpeg.pc missing + -DENABLE_CPP=NO), running cmake fails with:

> CMake Error at cmake/modules/FindLIBOPENJPEG.cmake:41 (check_cxx_source_compiles):
>   Unknown CMake command "check_cxx_source_compiles".
> Call Stack (most recent call first):
>   CMakeLists.txt:207 (find_package)

Adding "include(CheckCXXSourceCompiles)" to cmake/modules/FindLIBOPENJPEG.cmake
fixes this.

Tested with Poppler 0.60.0.
