Cmake 在使用配置包时，如何强制配置类型？

在具有自定义配置类型的cmake生成中，例如

RelWithAsserts

if(CMAKE_CONFIGURATION_TYPES)
    set(CMAKE_CONFIGURATION_TYPES Debug Release RelWithAsserts)
    set(CMAKE_CONFIGURATION_TYPES "${CMAKE_CONFIGURATION_TYPES}" CACHE STRING
        "Reset the configurations to what we need"
        FORCE)
endif()

如何通过

find_package

更改您使用的软件包的配置，并强制将其释放

# GTest doesn't have RelWithAsserts config type, so this wont work.
find_package(GTest CONFIG REQUIRED) 

# Somehow force this to use Release config.
target_link_libraries(test PRIVATE GTest::GTest)

ty

通过设置变量可以轻松调整导入目标的配置：

# When the project is built in RelWithAsserts configuration
# use Release version of IMPORTED targets
set(CMAKE_MAP_IMPORTED_CONFIG_RELWITHASSERTS Release)
# Now `find_package` could be used.
# It will create IMPORTED targets with needed properties
find_package(GTest CONFIG REQUIRED)

target_link_libraries(test PRIVATE GTest::GTest)

您甚至可以使用该设置：

# When the project is built in RelWithAsserts configuration
# use Release version of an IMPORTED target if it exists.
# If some target misses Release version, then fallback to Debug.
set(CMAKE_MAP_IMPORTED_CONFIG_RELWITHASSERTS Release Debug)
