I'm trying to configure CMake and ninja as a build system for my project. Except the app itself I have an extra executable for unit tests powered by gtest. I thought it would be nice to have them executed automatically whenever they are built. Here's how I made it:
├── build
└── source
├── CMakeLists.txt
├── main.cc
└── ut
├── CMakeLists.txt
├── gtest
│ ├── ...
└── ut.cc
source/CMakeLists.txt...
cmake_minimum_required (VERSION 2.6)
project (trial)
add_subdirectory(ut)
add_executable(trial main.cc)
...and source/ut/CMakeLists.txt:
add_subdirectory(gtest)
include_directories ("gtest/include")
add_executable(ut ut.cc)
target_link_libraries(ut LINK_PUBLIC gtest_main)
add_custom_target(run_uts
COMMAND ut
DEPENDS ut
WORKING_DIRECTORY ${CMAKE_PROJECT_DIR}
)
Now when I build it, i.e.:
cd build
cmake -GNinja ../source
ninja run_uts
It works fine except that the output is colorless. When I run the ut binary by hand, i.e. build/ut/ut
I get nice green and red colors. The colors are also there when I use Unix Makefiles as a genrator for CMake.
Since I'm only learning CMake, is there something I missed or is it an issue with Ninja?
