安装了带有自制软件的GTK+，但pkg_check_modules无法识别它

Question

我正在尝试编译一个开源的repo，这需要gtk+在CMakeLists.txt文件:

pkg_check_modules (GTK     REQUIRED gtk+-2.0>=2.12)

所以我安装了gtk+-2.0与homebrew:

~  brew install gtk
Warning: gtk+-2.24.23 already installed

和确保pkg-config识别它，我已经尝试:

~  pkg-config --modversion gtk+-2.0
2.24.23

这是完全正确的，但是当我用ccmake ..配置项目时，我得到了错误:

CMake Error at /usr/local/Cellar/cmake/2.8.12.2/share/cmake/Modules/FindPkgConfig.cmake:279 (message):
  A required package was not found
Call Stack (most recent call first):
  /usr/local/Cellar/cmake/2.8.12.2/share/cmake/Modules/FindPkgConfig.cmake:333 (_pkg_check_modules_internal)
  CMakeLists.txt:194 (pkg_check_modules)

我该如何解决这个问题?

Answer 1

你试过了吗

export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:$PKG_CONFIG_PATH

或

export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
