获取cmake和自制啤酒一起工作 [英] Get cmake and home-brew to work together

问题描述

当我安装库与homebrew cmake似乎无法找到他们。

When I install libraries with homebrew cmake can't seem to find them. Is there a simple way to fix this for an arbitrary library installed with brew.

推荐答案

默认

默认情况下，brew的库安装到 / usr / local / lib 文件夹：

> ls /usr/local/lib/liblzma.dylib 
/usr/local/lib/liblzma.dylib@

检查此路径是否存在于 CMAKE_SYSTEM_PREFIX_PATH 变量中。在这种情况下
find是微不足道的：

Check that this path exists in CMAKE_SYSTEM_PREFIX_PATH variable. In this case find is trivial:

message("system: ${CMAKE_SYSTEM_PREFIX_PATH}")
find_library(LZMA_LIBRARY lzma)
message("lzma: ${LZMA_LIBRARY}")

结果：

system: /usr/local;/usr;/;...
lzma: /usr/local/lib/liblzma.dylib

否则

如果不是，您需要修改 CMAKE_PREFIX_PATH 或 CMAKE_LIBRARY_PATH
之前find_library 命令：

list(APPEND CMAKE_PREFIX_PATH /usr/local)
