What's the difference between find_package(MPI) and FindMPI?

To fix this issue Because FindMPI is one of the Find Modules provided by the CMake installation, the find_package(MPI) and include(FindMPI) calls are essentially equivalent. (The include() is required here to load the module; simply writing FindMPI in a CMake file will result in an error.)
The find_package() command has two modes: MODULE and CONFIG. The default is MODULE mode, and from the find_package() documentation:

Hope this helps You would use the latter when a) not accessing an object or array for the value, and b) no characters follow the variable name that could possibly be interpreted as part of it.

Whats the difference between these difference cache-control params?

wish helps you no-cache
If the no-cache directive does not specify a field-name, then a cache MUST NOT use the response to satisfy a subsequent request without successful revalidation with the origin server. This allows an origin server to prevent caching even by caches that have been configured to return stale responses to client requests.

this one helps. The way to solve the CAPS in the CSS is a simple meta tag in the head.the caps in the script came from Quirks-mode. to stop the IE browser to use this mode use the meta tag shown here
code :
<!-- Enable IE9 Standards mode -->

what is the difference between find_package and pkg_search_module

it should still fix some issue pkg_search_module uses the pkg-config tool to determine the location of the requested library. This is mostly useful on systems where pkg-config is already in use, so you do not need to replicate all the information for CMake. Note that this approach has potential portability issues, since it requires pkg-config to be setup correctly on the build machine.
find_package on the other hand is CMake's very own mechanism for solving the same problem. For this to work you either need a CMake find script for the requested library (CMake already ships with a couple of those, but you can easily write your own) or alternatively a package config script provided by the requested library itself. In either case you might have to adjust your CMAKE_MODULE_PATH for CMake to be able to find the respective script.

I wish this help you According to documentation, find_dependency is just a wrapper around find_package:
