回复: QT5.15.2 编译qwebengine 支持mp4 求助！[已解决]

lixinwei:没有办法随心所欲地设置安装路径，但是有变通的办法
如：
nmake install INSTALL_ROOT=\temp假设你的Qt安装目录是D:\Qt\5.15.2\msvc2019，用这个命令可以安装到D:\temp\Qt\5.15.2\msvc2019，后续可以根据需要剪切到其他目录，这样就不会覆盖已有的文件了

如果编译整个Qt或者qtbase，可以设置prefix；但是如果单独编译qtbase以外的模块，如单独编译qtwebengine，是无法设置prefix的，但是可以用上述方法先把需要安装的文件安装到其他位置，以避免安装的时候已有的Qt5WebEngineCore.dll等文件被直接覆盖

好吧。。。。看来我基本没单独编译过模块，我都是全编译的
