cmake-查找忽略目录的路径

问题描述

在执行find_path时，如何使cmake忽略目录？我正在尝试找到系统的freetype2库，但实际上是在我的项目中找到了该库。

How do I make cmake ignore a directory when doing find_path? I'm trying to find the system's freetype2 library, but instead it is finding the one that inside my project. How do I get it to ignore that?

这是我的FindFreeTypeTwo.cmake的样子

Here's what my FindFreeTypeTwo.cmake looks like

FIND_PATH(_FREETYPE2_INCLUDE_DIR ft2build.h PATH_SUFFIXES freetype2)
FIND_LIBRARY(_FREETYPE2_LIBRARIES NAMES freetype)

INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(Freetype2 DEFAULT_MSG _FREETYPE2_LIBRARIES _FREETYPE2_INCLUDE_DIR)

if (FREETYPE2_FOUND)
   set (FREETYPE2_INCLUDE_DIR ${_FREETYPE2_INCLUDE_DIR})
   set (FREETYPE2_LIBRARIES ${_FREETYPE2_LIBRARIES})
endif (FREETYPE2_FOUND)

这就是我的文件结构。

  \
   \ src
    | CMakeLists.tst
     \ build
      \ cmake_config
       \ find_packages
        | FindFreeTypeTwo.cmake
   \ (folder to exclude)
   \ (other folders)

推荐答案

您可以在 FIND_PATH（）中更改参数。代替使用 PATH_SUFFIXES ，您可以使用类似
FIND_PATH（_FREETYPE2_INCLUDE_DIR ft2build.h提示ENV FREETYPE2_INCLUDE_DIR PATHS / usr / local /包括）
这是我编写cmake文件时通常使用的东西。

You could change the parameters in the FIND_PATH(). Instead of using the PATH_SUFFIXES, you could use something like thisFIND_PATH(_FREETYPE2_INCLUDE_DIR ft2build.h HINTS ENV FREETYPE2_INCLUDE_DIR PATHS /usr/local/include)This is something I usually use when I write cmake file.
