强制cmake FIND_LIBRARY在自定义目录中查找

更新时间:2023-02-03 12:51:17

您可以使用 NO_DEFAULT_PATH NO_CMAKE_ENVIRONMENT_PATH
中的一个或多个来指定搜索顺序, NO_CMAKE_PATH NO_SYSTEM_ENVIRONMENT_PATH NO_CMAKE_SYSTEM_PATH CMAKE_FIND_ROOT_PATH_BOTH ONLY_CMAKE_FIND_ROOT_PATH NO_CMAKE_FIND_ROOT_PATH

You can specify the search order using one or more of NO_DEFAULT_PATH, NO_CMAKE_ENVIRONMENT_PATH , NO_CMAKE_PATH, NO_SYSTEM_ENVIRONMENT_PATH, NO_CMAKE_SYSTEM_PATH, CMAKE_FIND_ROOT_PATH_BOTH, ONLY_CMAKE_FIND_ROOT_PATH, orNO_CMAKE_FIND_ROOT_PATH.

find_library


设计了默认搜索顺序项目可以通过简单地多次调用该命令并使用NO_ *选项来覆盖该命令,即可以覆盖特定的顺序。

The default search order is designed to be most-specific to least-specific for common use cases. Projects may override the order by simply calling the command multiple times and using the NO_* options:

find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
find_library(<VAR> NAMES name)

一旦调用成功,将设置结果变量并将其存储在缓存中,这样就不会再有搜索。

Once one of the calls succeeds the result variable will be set and stored in the cache so that no call will search again.

因此,您可以这样做

FIND_LIBRARY(APRUTIL NAMES "aprutil-1"
  PATHS ${PROJECT_SOURCE_DIR}/tools/apr/libs NO_DEFAULT_PATH)
