Rolf Eike Beer 745b56f58c Find*.cmake: drop the comments before including FPHSA
No need to explain this over and over again.  While at it, do some other
minor cleanups to whitespace and comments (i.e. delete them).

# Find Armadillo
#
# Find the Armadillo C++ library
#
# Using Armadillo:
#
# ::
#
# find_package(Armadillo REQUIRED)
# include_directories(${ARMADILLO_INCLUDE_DIRS})
# add_executable(foo foo.cc)
# target_link_libraries(foo ${ARMADILLO_LIBRARIES})
#
# This module sets the following variables:
#
# ::
#
# ARMADILLO_FOUND - set to true if the library is found
# ARMADILLO_INCLUDE_DIRS - list of required include directories
# ARMADILLO_LIBRARIES - list of libraries to be linked
# ARMADILLO_VERSION_MAJOR - major version number
# ARMADILLO_VERSION_MINOR - minor version number
# ARMADILLO_VERSION_PATCH - patch version number
# ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4")
# ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech")
# UNIX paths are standard, no need to write.
