# look for a stand alone cblas, please add the following in your
# CMakeLists.txt before to call find_package(CBLAS):
# set(CBLAS_STANDALONE TRUE)
+###
+# We handle different modes to find the dependency
+#
+# - Install from a tarball downloaded on internet (we decide the distribution to ensure compatibility)
+# - activate it with CBLAS_DOWNLOAD=ON
+# - will download and build NETLIB CBLAS: http://www.netlib.org/blas/blast-forum/cblas.tgz
+# - the resulting library is cblas_LINUX.a, see their Makafile.in !
+#
+# - Install from sources somewhere on the system:
+# - activate it with CBLAS_SOURCE_DIR=path/to/sources, note you manage your build configuration through the make.inc
+# - for now we handle the NETLIB cblas only, see http://www.netlib.org/blas/blast-forum/cblas.tgz, maybe more in the future
+#
+# - Detection if already installed on the system
+# - CBLAS libraries can be detected from different ways
+# Here is the order of precedence:
+# 1) we look in cmake variable CBLAS_LIBDIR or CBLAS_DIR (we guess the libdirs) if defined
+# 2) we look in environnement variable CBLAS_LIBDIR or CBLAS_DIR (we guess the libdirs) if defined
+# 3) we look in common environnment variables depending on the system (INCLUDE, C_INCLUDE_PATH, CPATH - LIB, DYLD_LIBRARY_PATH, LD_LIBRARY_PATH)
+# 4) we look in common system paths depending on the system, see for example paths contained in the following cmake variables:
+# - CMAKE_PLATFORM_IMPLICIT_INCLUDE_DIRECTORIES, CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES
+# - CMAKE_C_IMPLICIT_INCLUDE_DIRECTORIES, CMAKE_C_IMPLICIT_LINK_DIRECTORIES
