Out of memory error caused by linalg with vs2017

[OXPHOS]

The linalg headers are causing C1060: out of heap space error when compiling with VS2017 on Appveyor consistently now. (Traced back to 2 months ago).

The closest solution I found here suggested that /Zmfactor option can be added to limit the pre-allocated memory.

The way I tried that I felt should work is (but I am not completely sure) modifying CMakeLists:

IF(MSVC)
	SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /Zm1 ")
ELSE()
	SET(COMPILER_WARNINGS "-Wall -Wno-unused-parameter -Wformat -Wformat-security -Wparentheses -Wshadow -Wno-unknown-pragmas -Wno-deprecated")
ENDIF()

Zm1 is taken as a valid option by VS2017 but I still got C1060 error. So I have no clue how to fix it unless we refactor the macro structures.

Based on the assumption that the problem is caused by the numerous header in linalg lib.

140a8eb is hopefully fixing this... let's see couple of builds. but basically disabled VS2017 for the time being (as it takes way too much time to run one job) & disabled parallel build, this way hopefully there's more memory left for building the given source file.

feel free to reopen if you start to see this again ;)

ok this should be done as @micmn divided up the files....
