针对复杂构建过程的CMake设置建议（包括externalProject）

标签： cmake

我的应用程序具有相当复杂的构建过程，作为CMake的一个新手，我想知道是否有人可以提供任何指针。

在预设时，应用程序包含一个可执行文件，它是从src中提供的源代码树构建的，包含文件夹。

它需要一些库来工作，最重要的是Boost和Python。 Python嵌入在应用程序中，Boost需要在编译时了解自定义python安装。我也使用Qt，但我只是为此系统Qt链接。

最后我想要的是一个stage文件夹，包含已编译的可执行文件，以及一个包含所需boost和python库的lib文件夹。

目前，我有一个CMakeLists.txt文件，我正在使用ExternalProject从源代码的bzipped tarball构建Boost和Python。我从前缀的安装目录中复制出已编译的库，这有点乱。

事情正在发挥作用，但我有一种感觉，我正在做一些倒退的事情。我有时在嵌套子目录中看到多个CMakeLists，但不知道它们与我的项目有什么关系。那些曾经从事类似范围项目的人是否能够权衡并给我一些指示？

我应该补充一点，我希望在不久的将来将Windows作为一个平台，并且目前正在Linux上运行。

注意：这是我当前的CMakeLists.txt，我意识到未配置boost并且没有完全移动到stage文件夹。我一直在手动这样做，但在我深入挖掘自己之前我想先问一下：）

谢谢！
