# This script gets the latest source code for the given program and compiles it.
# The name of the program, used for the folder names:
prog="hdrmerge"
# The name of the compiled executable:
exe="${prog}"
# The name of the sub-folder, if any, relative to the folder into which the
# compiled executable is placed.
# e.g. If the executable ends up in:
# ~/programs/someProgram/foo/bar/someExecutable
# then set it to:
# exeRelativePath="foo/bar"
# or if the executable ends up in
# ~/programs/someProgram/someExecutable
# then leave it empty:
# exeRelativePath=""
exeRelativePath=""
# The path to the repository:
repo="https://github.com/jcelaya/hdrmerge.git"
# No touching below this line, with the exception of the "Compile" section
# -----------------------------------------------------------------------------
# The name of the project's standard branch, typically "master":

# Removes the trailing forward-slash if one is present
exeRelativePath="${exeRelativePath/%\/}"
# Append forward-slash to exeRelativePath only if it is not empty.
