Add GTest #17

Closed marip8 closed 3 years ago

marip8 commented 3 years ago

This PR adds a CMake file (from here) for finding GTest and creating the targets

Levi-Armstrong commented 3 years ago

I believe the following should also be added to the cmake.in file

find_dependency(GTest)
if(NOT TARGET GTest::GTest)
  find_package(Threads QUIET)

  add_library(GTest::GTest INTERFACE IMPORTED)
  set_target_properties(GTest::GTest PROPERTIES INTERFACE_INCLUDE_DIRECTORIES "${GTEST_INCLUDE_DIRS}")
  if(TARGET Threads::Threads)
      set_target_properties(GTest::GTest PROPERTIES INTERFACE_LINK_LIBRARIES "${GTEST_LIBRARIES};Threads::Threads")
  else()
    set_target_properties(GTest::GTest PROPERTIES INTERFACE_LINK_LIBRARIES "${GTEST_LIBRARIES}")
  endif()
endif()

if(NOT TARGET GTest::Main)
  add_library(GTest::Main INTERFACE IMPORTED)
  set_target_properties(GTest::Main PROPERTIES INTERFACE_LINK_LIBRARIES "${GTEST_MAIN_LIBRARIES};GTest::GTest")
endif()
