我下载了matplotlib-cpp 我创建了一个 CMakeList.txt 来构建它。CmakeList.txt 的内容
project(myproject)
find_package(Python2 COMPONENTS Development NumPy)
target_include_directories(myproject PRIVATE ${Python2_INCLUDE_DIRS} ${Python2_NumPy_INCLUDE_DIRS})
target_link_libraries(myproject Python2::Python Python2::NumPy)
但是我一按下命令cmake ../就会收到这个错误

我可以就这个问题获得一些帮助吗？我认为问题在于名字myproject
