When we use MSVC to build static libraries, enabling LTCG will generate very large output, for example, Qt's bundled 3rd party libraries can be greater than 100MB per file (some of them even >200MB!). This is not good if we are building a shared version of Qt and enabling LTCG at the same time. On Windows Qt's bundled 3rd party dependencies will be built as static libraries and they will make the final Qt package way too large. From my side, if I only build a release version, the package size is usually around 500MB but when LTCG is enabled, it become over 2GB. The exe and dlls' size don't vary much, but there are many large static libraries.
