Setting up GMock with CMAKE (and Doxygen and ...)

[Adam Getchell]

I'd like to integrate GMock into my CMakeLists.txt for my project:

https://github.com/acgetchell/CDT-plusplus

I've read over:

http://stackoverflow.com/questions/11921089/add-an-external-source-directory-to-a-cmake-build

Just doing the basic setup of including:

################################################################################

# GTest - http://code.google.com/p/googlemock/

################################################################################

add_subdirectory(gmock-1.7.0)

enable_testing(true)

include_directories(${gmock_SOURCE_DIR}/include ${gmock_SOURCE_DIR})

Results in the following compilation error for main.cpp:

┌─[getchell][Hapkido][±][master ✓][~/CDT-plusplus]

Suggestions to fix this? Better yet, directions for building GMock in a build directory instead of adding it to my source files?

Thanks for any pointers,

Adam

After reading "Modern C++ Programming with Test-Driven Development", and most crucially, the errata, along with David Alfonso's GMock/CMAKE github project skeleton:

https://github.com/davidag/gtestmock-cmake-template

I've gotten this to work.

The only hangup now is getting Travis CI to build and link to GMock successfully:

https://travis-ci.org/acgetchell/CDT-plusplus

Got Travis CI and GMock to work together, by setting GMOCK_HOME="$TRAVIS_BUILD_DIR/gmock-1.7.0"
