cmake - 使用CMake构建外部项目时如何不进行安装步骤

Question

我正在使用cmake ExternalProject_Add命令构建依赖项项目:

include(ExternalProject)
...
set(COMMON_BASE_PROJECT_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../CommonBase)

ExternalProject_Add(CommonBaseProject
  SOURCE_DIR ${COMMON_BASE_PROJECT_DIR}
  BINARY_DIR ${COMMON_BASE_PROJECT_DIR}/build
  INSTALL_COMMMAND ""
)   

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
include_directories(${COMMON_BASE_PROJECT_DIR}/include)

add_library(
    ${LIBRARY_NAME}
    SHARED
    ${SRC_FILES}
    ${INCLUDE_FILES}
)

target_link_libraries (Bios ${COMMON_BASE_PROJECT_DIR}/build/libCommonBase.dll)
add_dependencies(Bios CommonBaseProject)

但我得到错误:

[100%] Linking CXX shared library libCommonBase.dll
[100%] Built target CommonBase
[ 50%] Performing install step for 'CommonBaseProject'
make[3]: *** No rule to make target 'install'.  Stop.

我不需要执行安装步骤，所以我的问题是:如何禁用它？

Answer 1

您可以使用STEP_TARGETS build为构建步骤生成目标，并添加对此特定目标的依赖性。步骤目标被命名为<external-project-name>-<step-name>，因此在这种情况下，代表构建步骤的目标将被命名为CommonBaseProject-build。

您可能还想通过EXCLUDE_FROM_ALL TRUE从“所有”目标中排除CommonBaseProject。

ExternalProject_Add(CommonBaseProject
  SOURCE_DIR ${COMMON_BASE_PROJECT_DIR}
  BINARY_DIR ${COMMON_BASE_PROJECT_DIR}/build
  STEP_TARGETS build
  EXCLUDE_FROM_ALL TRUE
)

add_dependencies(Bios CommonBaseProject-build)
