# - Find Java
|
|
# This module finds if Java is installed and determines where the
|
|
# include files and libraries are. This code sets the following
|
|
# variables:
|
|
#
|
|
# Java_JAVA_EXECUTABLE = the full path to the Java runtime
|
|
# Java_JAVAC_EXECUTABLE = the full path to the Java compiler
|
|
# Java_JAR_EXECUTABLE = the full path to the Java archiver
|
|
# Java_VERSION_STRING = Version of the package found (java version), eg. 1.6.0_12
|
|
# Java_VERSION_MAJOR = The major version of the package found.
|
|
# Java_VERSION_MINOR = The minor version of the package found.
|
|
# Java_VERSION_PATCH = The patch version of the package found.
|
|
# Java_VERSION_TWEAK = The tweak version of the package found (after '_')
|
|
# Java_VERSION = This is set to: $major.$minor.$patch(.$tweak)
|
|
#
|
|
# NOTE: ${Java_VERSION} and ${Java_VERSION_STRING} are not guaranteed to be
|
|
# identical. For example some java version may return:
|
|
# Java_VERSION_STRING = 1.5.0_17
|
|
# and
|
|
# Java_VERSION = 1.5.0.17
|
|
#
|
|
# another example is the Java OEM, with:
|
|
# Java_VERSION_STRING = 1.6.0-oem
|
|
# and
|
|
# Java_VERSION = 1.6.0
|
|
#
|
|
# NOTE: At the moment this script will look for javac and jar component,
|
|
# which means it will fail if javac or jar is not found.:w
|
|
# See Bug #9840
