 If you only need to inline versions, you don't need to build **cglm**, you don't need to link it to your program.
 Just import cglm to your project as dependency / external lib by copy-paste then use it as usual

+**make** will build cglm to **build** folder.
+If you don't want to install **cglm** to your system's folder you can get static and dynamic libs in this folder.
