如你所见,这是一个C++ Cmake Qt项目。
我想将外部项目添加到我的项目中。这个外部项目就是one。正如您所看到的,外部项目使用Makefile来构建自己,而不是使用cmake。在他们的自述文件中,它说要构建项目,请运行make LZMA=0 ZSTD=0 MD5=0
来构建它。
如果我手动构建它,就没有问题。
要将此项目作为外部项目添加到我的项目中,我添加了以下行:
include(ExternalProject)
ExternalProject_Add(HDiffPatch
SOURCE_DIR ${CMAKE_SOURCE_DIR}/dep/hdiffpatch
DOWNLOAD_COMMAND ""
UPDATE_COMMAND ""
CMAKE_ARGS
-DCMAKE_INSTALL_PREFIX=<INSTALL_DIR>
-DCMAKE_CXX_FLAGS=${CMAKE_CXX_FLAGS}
-DCMAKE_C_FLAGS=${CMAKE_C_FLAGS}
-DCMAKE_BUILD_TYPE=${CMAKE_BUILD_TYPE}
${USE_PROJECT_CMAKE_MODULE_PATH}
INSTALL_COMMAND "make LZMA=0 ZSTD=0 MD5=0")
当我尝试从Clion构建目标HDiffPatch时,我得到以下错误:
cmake-build-debug --target HDiffPatch -- -j 10
[ 12%] Creating directories for 'HDiffPatch'
[ 25%] No download step for 'HDiffPatch'

CMake Error: The source directory "/Users/venelin/Development/BeastBurst-Launcher/dep/hdiffpatch" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
make[3]: *** [HDiffPatch-prefix/src/HDiffPatch-stamp/HDiffPatch-configure] Error 1
make[2]: *** [CMakeFiles/HDiffPatch.dir/all] Error 2
make[1]: *** [CMakeFiles/HDiffPatch.dir/rule] Error 2
make: *** [HDiffPatch] Error 2
如何解决这个问题,如何链接HDiffPatch
,以便在项目中将其用作库,并从项目代码库执行其功能?

ExternalProject的标准步骤由CONFIGURE_COMMAND、BUILD_COMMAND、INSTALL_COMMAND选项表示。默认情况下,每个这样的步骤都使用适当的参数调用
cmake
。对于构建非CMake项目,您需要将这些选项重新定义到所需的命令行。例如至于在主项目中使用外部项目的工件,这种用法不依赖于外部项目的类型(CMake或非CMake),并解释为例如。在that answer中。
