This could be due to the level of optimization that you use when
compiling. For a true comparison, you might need to manually compile
the 2.1.x branch (which also should support Qt 5) with the same level of
optimization.
Note also that there are many other compilations flags that you can set.
You can see them at the end of the output of your "cmake
/path/to/source" command. As an example of how to set them, below is my
cmake command:
cmake "${gitRepoDIR}/" \
-DCMAKE_INSTALL_PREFIX=/usr/local/lyx-master \
-DLYX_DEBUG=ON -DLYX_RELEASE=OFF -DLYX_CPACK=ON \
-DLYX_PROGRAM_SUFFIX=ON -DLYX_LOCALVERSIONING=ON \
-DCPACK_BINARY_RPM:BOOL=OFF -DCPACK_BINARY_DEB:BOOL=ON \
-DCPACK_BINARY_NSIS:BOOL=OFF -DCPACK_BINARY_STGZ:BOOL=OFF \
-DCPACK_BINARY_TGZ:BOOL=OFF -DCPACK_BINARY_TBZ2:BOOL=OFF \
-DCPACK_BINARY_TZ:BOOL=OFF -DCPACK_SOURCE_TBZ2:BOOL=OFF \
-DCPACK_SOURCE_TGZ:BOOL=ON -DCPACK_SOURCE_TZ:BOOL=OFF \
-DCPACK_SOURCE_ZIP:BOOL=OFF -DLYX_EXTERNAL_BOOST=OFF \
-DLYX_HUNSPELL=ON -DLYX_ENCHANT=ON -DLYX_NLS=ON \
-DLYX_ENABLE_CXX11=ON \
-DLYX_ENABLE_URLTESTS=ON \
-DLYX_ENABLE_EXPORT_TESTS=ON \
-DLYX_USE_QT=QT5 -DLYX_CXX_FLAGS_EXTRA="${CPPFLAGS}"
where gitRepoDIR and CPPFLAGS are my own defined variables.
There are equivalents when building with autotools.
