 ## Build instructions
 Building the library is simple:
 ```
-INSTALL_ROOT=/where/you/want/to/install qmake-qt5 "c++utilities.pro" -r -spec linux-g++
+INSTALL_ROOT=/where/you/want/to/install qmake-qt5 c++utilities.pro
 make && make install
 ```
 As you can see, the qmake build system is used. However the library itself does *not* depend on Qt.
 
+It is also possible to build the library using CMake:
+```
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/where/you/want/to/install project/directory
+make && make install
+```
+
+In any case, the make option *-j* might be used to compile multiple files in parallel.
+
 The repository PKGBUILDs (also on GitHub) contains files for building Arch Linux packages. A PKGBUILD file to build for Windows using the Mingw-w64 compiler is also included.
