如何使用qt的自定义路径构建cmake gui？

我正在尝试使用自定义路径构建

cmake gui

，但在运行时失败：

#/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CmakeGUI开始在/opt/dev-tools-4.9搜索qtX，但它是从系统中使用的

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

我在一个示例中发现，我可以使用qtX的自定义路径：

如果Qt4和Qt5安装在/opt中，请使用源setqt4或源 设置qt5以选择用于构建基于Qt的GUI的选项

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，应在

添加可执行文件（cmake gui…）

之后，向

源代码/QtDialog/CMakeLists.txt

中添加类似的内容：

不要忘记完全重新生成CMake构建文件。正确配置的生成应该在

Source/QtDialog/CMakeFiles/cmakegui.dir/link.txt中的链接器调用命令中包含
-Wl，-rpath，

注意：所有内容都是根据cmake-3.2.2进行检查的，但我认为cmake的其他版本在这方面没有显著差异。
好的，您应该在构建过程中使用
-rpath
链接器选项，或者在执行之前将libs的路径添加到LD_LIBRARY_path环境变量。如果键入
ls/opt | grep qt
，会得到什么？我不知道LFS，但似乎在开始构建cmake之前必须运行
源代码setqt4
，所以它不是cmake的一部分？
set_target_properties(cmake-gui PROPERTIES                
  INSTALL_RPATH "/opt/path/to/qt/shared/libs"
)
