我的CMakeList有问题吗?

Is there something wrong with my CMakeLists?

本文关键字：有问题 CMakeList 我的      更新时间：2023-10-16

以下是我的CMakeLists文件。默认情况下，我希望它定义agui_allegro5库中的符号ALLEGRO_STATICLINK，但它没有，但是当我检查WANT_SHARED它定义它时，它不应该定义它，但没有定义AGUI_BACKEND_BUILD它应该。我的逻辑有缺陷还是什么？

谢谢

根据 CMake 文档"DEFINE_SYMBOL设置在共享库中编译源代码时定义的预处理器符号的名称"，而您尝试在静态库上使用它，因此没有效果。您可能还会发现此讨论很有用。

Cmake 文档说属性DEFINE_SYMBOL只为共享库参加，请尝试使用COMPILE_DEFINITIONS属性。
