Allow for a different unittest path

[RichardWarburton]

Thanks for filing the issue. IIRC using pkgconfig to lookup unittest++ didn't work out so well for me, so is there a particular way you would like to have the include set? Eg: would you want to set an environment variable which overrides the unittest include?

[rombert]

I have little knowledge of Makefiles and pkgconfig, but a environment variable override sounds fine.

Same issue on Mac, I hacked the CMakeLists.txt to use my own unittest++

See #1 for more details

[RichardWarburton]

@rombert can you confirm that the move to cmake has fixed this issue on your distro?

@Pyrolistical what changes did you make to CMakeLists.txt in order to get things to work on a mac?

#1 links to a method for pulling down external source dependencies and building them using cmake - though I've never done this before. This seems like a more general solution.

[Pyrolistical]

@RichardWarburton I've added my hack to CMakeLists.txt in #1

[rombert]

@RichardWarburton - for some reason this still does not work.

$ cmake CMakeLists.txt 
-- checking for module 'unittest++'
--   package 'unittest++' not found
CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:341 (message):
  A required package was not found
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPkgConfig.cmake:395 (_pkg_check_modules_internal)
  CMakeLists.txt:33 (pkg_check_modules)


-- using GCC
-- Configuring incomplete, errors occurred!

Is there any way I can help debug this? For the record, the headers live in /usr/include/unittest-cpp and the .a file is in /usr/lib64 .

[RichardWarburton]

@rombert have you tried deleting CMakeCache.txt and re-running cmake CMakeLists.txt?

[rombert]

@RichardWarburton - thanks, but that still did not help.

[RichardWarburton]

@rombert I've added parameters for this for you. For example on ubuntu you would write the following to manually set UnitTest++:

UNITTEST_INCLUDE_DIRS="/usr/include/unittest++/" UNITTEST_LIBRARIES="UnitTest++" cmake CMakeLists.txt

If nothing appears to be different, try cleaning the cache - rm -rf CMakeCache.txt CMakeFiles/

[rombert]

UNITTEST_INCLUDE_DIRS="/usr/include/unittest-cpp" UNITTEST_LIBRARIES="UnitTest++" cmake CMakeLists.txt 

worked for me, thank you!
