我有一个带有2个变体的程序包,具有以下目录结构
pkg
pkg_main.h
CMakeLists.txt
var1
pkg_main.cpp
var2
pkg_main.cpp
conanfile.py
对于conan,我试图定义一个选项fileSelection
,其值可能为var1
和var2
。
使用cmake,我尝试按以下方式进行选择:如果fileSelection
设置为var1
,则将调用var1/pkg_main.cpp
,否则将调用var2/pkg_main.cpp
。
到目前为止,我已经在fileSelection
中定义了选项conanfile.py
class PkgConan(ConanFile):
name = "pkg"
...
options = {"fileSelection : ['var1', 'var2']"}
default_options = "fileSelection=var1"
generators = "cmake"
def build(self):
cmake = CMake(self)
cmake.configure(source_folder="pkg")
cmake.build()
def package(self):
self.copy("*.h", dst="include", src="pkg")
self.copy("*pkg.lib", dst="lib", keep_path=False)
self.copy("*.dll", dst="bin", keep_path=False)
self.copy("*.so", dst="lib", keep_path=False)
self.copy("*.dylib", dst="lib", keep_path=False)
self.copy("*.a", dst="lib", keep_path=False)
def package_info(self):
self.cpp_info.libs = ["pkg"]
现在,我正在努力更新CMakeLists.txt
文件以根据fileSelection
的值进行选择。像这样的东西:
[这是逻辑,而不是可运行的代码]
if("${fileSelection}" STREQUAL "var1")
add_library(pkg var1/pkg_main.cpp)
else
add_library(pkg var2/pkg_main.cpp)
endif
?? 如何将fileSelection
选项传递给cmake;在哪里以及如何实现var1
和var2
之间的切换(通过尝试在CMakeLists.txt中定义切换,我朝着正确的方向前进)吗?
答案 0 :(得分:2)
您可以将变量传递给由cmake助手驱动的cmake命令行调用。像这样:
options = {"fileSelection": ["var1", "var2"]}
...
def build(self):
cmake = CMake(self)
cmake.definitions["fileSelection"] = self.options.fileSelection
cmake.configure(source_folder="pkg")
cmake.build()
假定您具有所描述的CMakeLists.txt逻辑。
