googlemock error on build: No rule to make target

[wtjones]

Running the following:

mkdir build
cd build
cmake ..
make

Results in this error:

 11%] Built target libfoo
[ 23%] Built target libbar
[ 35%] Built target myApp
[ 82%] Built target gtest
make[2]: *** No rule to make target 'test/gtest/src/gtest-build/googlemock/gtest/libgtest.a', needed by 'test/testfoo/testfoo'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:233: test/testfoo/CMakeFiles/testfoo.dir/all] Error 2
make: *** [Makefile:141: all] Error 2

The issue can be resolved by editting the CMakeLists.txt from the test directory. The corrected code piece:

set_target_properties(libgtest PROPERTIES
"IMPORTED_LOCATION" "${binary_dir}/lib/libgtest.a"
"IMPORTED_LINK_INTERFACE_LIBRARIES" "${CMAKE_THREAD_LIBS_INIT}"
)

set_target_properties(libgmock PROPERTIES
"IMPORTED_LOCATION" "${binary_dir}/lib/libgmock.a"
"IMPORTED_LINK_INTERFACE_LIBRARIES" "${CMAKE_THREAD_LIBS_INIT}"
)`

Specifically the two locations that "IMPORTED_LOCATION" are set for gtest and gmock were incorrect. The above seems to work.

I needed to add this to the root CMakeLists.txt:

specify the C++ standard

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)
