not all made it in this document.
While at it, removed all kinds of Markdown warnings by an excessive
usage of spacebar in this document.

FindICU
-------
Finds components of the ICU library.
Accepted components are: uc, i18n, le, lx, io
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``ICU_FOUND``
True if components of ICU library are found.
``ICU_VERSION``
The version of the ICU library which was found.
``ICU_<c>_FOUND``
True if the system has the <c> component of ICU library.
``ICU_<c>_INCLUDE_DIRS``
Include directories needed to use the <c> component of ICU library.
``ICU_<c>_LIBRARIES``
Libraries needed to link to the <c> component of ICU library.
