当项目的repo不是我想要使用的库的根目录时,如何在CMake中添加外部项目,但实际上包含两个目录,这些目录是我想要的repos的根目录在我的项目中使用?
我正在努力建立一个使用Google Test和Mock进行测试的框架CMake项目,但是当我尝试使用ExternalProject_Add
下载google test repo(https://github.com/google/googletest)时,在构建上抱怨它无法找到项目的来源。嗯,这是因为Google已将googletest和googlemock合并为一个项目,除了它现在有两个项目。
一些repo的文件结构:
googletest-master/
├──[...no CMakeFiles.txt exists here...]
├──googletest/
│ ├──src/
│ └──CMakeFiles.txt
└──googlemock/
├──src/
└──CMakeFiles.txt
当我做以下事情时......
ExternalProject_Add(
gtest
GIT_REPOSITORY https://github.com/google/googletest.git
TIMEOUT 10
INSTALL_COMMAND ""
LOG_DOWNLOAD ON
LOG_CONFIGURE ON
LOG_BUILD ON
PREFIX "googletest-master"
)
...它会将实际回购下载到googletest-master/src/gtest
,因为我在回购商的前面添加" googletest-master"保持它不受我的主要源代码的影响,它假定我下载的项目只是源代码而且该源代码位于根目录中。
所以我想完成两件事:

您需要单个下载步骤,但两个构建步骤。不同的ExternalProject_add
命令调用不能共享步骤,但您可以将所有这些步骤安排到不同的调用中,并在它们之间具有适当的依赖关系:
# Single download(git clone)
ExternalProject_Add(
googletest-master
DOWNLOAD_DIR "googletest-master/src" # The only dir option which is required
GIT_REPOSITORY https://github.com/google/googletest.git
TIMEOUT 10
LOG_DOWNLOAD ON
# Disable all other steps
CONFIGURE_COMMAND ""
BUILD_COMMAND ""
INSTALL_COMMAND ""
)
# Build gtest from existing sources
ExternalProject_Add(
gtest
DOWNLOAD_COMMAND "" # No download required
SOURCE_DIR "googletest-master/src/googletest" # Use specific source dir
PREFIX "googletest-master" # But use prefix for compute other dirs
INSTALL_COMMAND ""
LOG_CONFIGURE ON
LOG_BUILD ON
)
# gtest should be build after being downloaded
add_dependencies(gtest googletest-master)
# Build gmock from existing sources
ExternalProject_Add(
gmock
DOWNLOAD_COMMAND "" # No download required
SOURCE_DIR "googletest-master/src/googlemock" # Use specific source dir
PREFIX "googletest-master" # But use prefix for compute other dirs
INSTALL_COMMAND ""
LOG_CONFIGURE ON
LOG_BUILD ON
)
# gmock should be build after being downloaded
add_dependencies(gmock googletest-master)

我有一个repository,我可以根据需要使用CMake导入gtest和gmock库,但是使用旧的SVN源代码库而不是GIT。
我认为关键是只为gmock获取源代码,因为它包含gtest源,然后导出两个库。
CMakeLists.txt看起来像这样:
cmake_minimum_required(VERSION 2.8)
include(ExternalProject)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(GMOCK_VERSION "1.7.0")
set(GMOCK_DIR "${CMAKE_CURRENT_BINARY_DIR}/gmock-${GMOCK_VERSION}")
ExternalProject_Add(project_gmock
SVN_REPOSITORY http://googlemock.googlecode.com/svn/tags/release-${GMOCK_VERSION}
PREFIX ${GMOCK_DIR}
CMAKE_ARGS -DCMAKE_C_COMPILER:PATH=${CMAKE_C_COMPILER} -DCMAKE_CXX_COMPILER:PATH=${CMAKE_CXX_COMPILER}
# Disable update step
UPDATE_COMMAND ""
# Disable install step
