#  CMake script for the step-17 tutorial program:

# Set the name of the project and target:
SET(TARGET "solver")
set(CMAKE_CXX_STANDARD 14)
# Declare all source files the target consists of. Here, this is only
# the one step-X.cc file, but as you expand your project you may wish
# to add other source files as well. If your project becomes much larger,
# you may want to either replace the following statement by something like
#  FILE(GLOB_RECURSE TARGET_SRC  "source/*.cc")
#  FILE(GLOB_RECURSE TARGET_INC  "include/*.h")
#  SET(TARGET_SRC ${TARGET_SRC}  ${TARGET_INC})
# or switch altogether to the large project CMakeLists.txt file discussed
# in the "CMake in user projects" page accessible from the "User info"
# page of the documentation.
FILE(GLOB_RECURSE TARGET_SRC "src/*.cpp" "src/*.hpp" "src/*.h")
SET(TARGET_SRC ${TARGET_SRC} ${TARGET_INC})

#SET(TARGET_SRC
#        ${TARGET}.cc
#        )

# Usually, you will not need to modify anything beyond this point...
