#Parse Semantic Version

semver_parse() parses a semantic version string and assigns the various version parts to the provided output variable.

#Example

include("rsp/version")

semver_parse(
    VERSION "v2.0.0-beta.3+AF1004"
    OUTPUT my_package
)

# (see example output below...)

#Output

The [OUTPUT] variable will contain the full version string, as it was provided:

message("${my_package}") # v2.0.0-beta.3+AF1004

#Major, Minor and Patch

The [OUTPUT]_VERSION variable contains a CMake friendly version string (major.minor.patch)

message("${my_package}_VERSION") # 2.0.0

#Semantic Version
