# LIB_PREFIX: LWESP
#
# This file provides set of variables for end user
# and also generates one (or more) libraries, that can be added to the project using target_link_libraries(...)
#
# Before this file is included to the root CMakeLists file (using include() function), user can set some variables:
#
# LWESP_SYS_PORT: If defined, it will include port source file from the library, and include the necessary header file.
# LWESP_OPTS_FILE: If defined, it is the path to the user options file. If not defined, one will be generated for you automatically
# LWESP_COMPILE_OPTIONS: If defined, it provide compiler options for generated library.
# LWESP_COMPILE_DEFINITIONS: If defined, it provides "-D" definitions to the library build
#
