如何使用qt的自定义路径构建cmake-gui？

Question

我想建立cmake-gui与自定义路径，但是失败的运行：

#/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 

所以我想这cmake的桂开始在/opt/dev-tools-4.9搜索QTX，但它从一个用系统

# strace -f ./cmake-gui 
execve("./cmake-gui", ["./cmake-gui"], [/* 24 vars */]) = 0

我在LFS找到一个例子，其中我可以使用自定义路径QTX：

如果Qt4​​的和QT5被安装在/ opt，使用源setqt4或源码 setqt5选择哪一个将用于构建基于Qt的GUI。

但没有这些文件：

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

libarchive

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的构建2.8.11

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

要调整的是rpath的构建只适用于cmake-gui，您应该在之后添加这样的内容，后add_executable(cmake-gui....)：

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

不要忘记再生CMake的完全建立的文件。一个正确配置的版本应该在链接器调用命令中包含-Wl,-rpath,<specified-path>Source/QtDialog/CMakeFiles/cmake-gui.dir/link.txt

注意：一切都按照cmake-3.2.2进行检查，但我不认为其他版本的cmake在这方面有很大不同。
