Question

我正在尝试使用自定义路径构建cmake-gui并且在运行时失败：

#/opt/dev-tools-4.9/cmake-gui
/opt/dev-tools-4.9/cmake-gui: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

所以我希望cmake-gui开始在/opt/dev-tools-4.9搜索qtX，但它是从系统中使用的

我在LFS中找到了一个示例，我可以使用qtX的自定义路径：

如果在/ opt中安装了Qt4和Qt5，请使用source setqt4或source setqt5选择将用于构建基于Qt的GUI。

但是没有那些文件：

~# cd cmake-3.5.2
root:~/cmake-3.5.2# ls |grep set
root:~/cmake-3.5.2#

libarchive的构建

wget http://www.libarchive.org/downloads/libarchive-3.2.0.tar.gz
tar xzvf  libarchive-3.2.0.tar.gz
./configure --prefix=/opt/dev-tools-4.9 --disable-static && \
make -j $(nproc || grep -c ^processor /proc/cpuinfo|| echo "1") && \
make install

cmake 2.8.11的构建

wget --no-check-certificate https://cmake.org/files/v2.8/cmake-2.8.11.tar.gz
tar xzvf cmake-2.8.11.tar.gz
./bootstrap --prefix=/opt/dev-tools-4.9   \
  --no-system-libs --qt-gui         && \
  make -j $(nproc || grep -c ^processor /proc/cpuinfo|| echo "1") && \
  make install

要仅调整cmake-gui的rpath，您应该在Source/QtDialog/CMakeLists.txt后添加add_executable(cmake-gui....)的内容：

set_target_properties(cmake-gui PROPERTIES                
  INSTALL_RPATH "/opt/path/to/qt/shared/libs"
)

不要忘记完全重新生成CMake构建文件。正确配置的构建应在-Wl,-rpath,<specified-path>

中的链接器调用命令中包含Source/QtDialog/CMakeFiles/cmake-gui.dir/link.txt

注意：所有内容都是根据cmake-3.2.2进行检查的，但我不认为其他版本的cmake在这方面存在显着差异。

如何用qt的自定义路径构建cmake-gui？
