You need to use the value (${arg1} ${arg2}) of the arguments and not
the arg name itself.
Try this:
macro(my_find_library arg1 arg2)
message(arg1)
message(arg2)
message("arg1 = ${arg1}")
message("arg2 = ${arg2}")
endmacro(my_find_library)
my_find_library(TOTO titi)
If you need more example of MACRO usage you look at
CMake distros modules directory.
For example:
CheckTypeSize.cmake
CheckFunctionExists.cmake
or any other containing MACRO.
