GTest首先在CMake建立

Question

我正在构建动态库，并希望使用gtest进行测试。

SET(GTEST_LIBRARY libs/googletest-master)
set(GTEST_INCLUDE_DIR libs/googletest-master/googletest/include)
#set(GTEST_MAIN_LIBRARY libs/googletest-master/googletest/include/gtest)

#find_package(PostgreSQL REQUIRED)

enable_testing()
find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIR})

但是，berofe设置GTEST_MAIN_LIBRARY我必须首先构建它。 我如何配置CMake来实现这个目标

1. 使用Cmake＆amp;＆amp ;;构建gtest make（在unix上）
2. 获取GTEST_MAIN_LIBRARY
的相应路径
3. 继续构建

Answer 1

I copied gtests srcs into project make a build with Make and add this to CMake

add_subdirectory(libs/googletest-master)

SET(GTEST_LIBRARY libs/googletest-master)
set(GTEST_INCLUDE_DIR libs/googletest-master/googletest/include)
set(GTEST_MAIN_LIBRARY libs/googletest-master/googlemock/gtest)

enable_testing()
find_package(GTest REQUIRED)
include_directories(${GTEST_INCLUDE_DIR})
include_directories(${gtest_SOURCE_DIR}/include ${gtest_SOURCE_DIR})

Answer 2

如果您将googletest的源代码放在CMakeLists.txt文件所在的子目录中，则以下内容应该有效：

add_subdirectory(./googletest)

add_executable(your_program ${MY_SRC})

add_dependencies(your_program gmock)
add_dependencies(your_program gtest)
