# --------

|
|
# Find Java
|
|
#
|
|
# This module finds if Java is installed and determines where the
|
|
# include files and libraries are. The caller may set variable JAVA_HOME
|
|
# to specify a Java installation prefix explicitly.
|
|
#
|
|
# This module sets the following result variables:
|
|
#
|
|
# ::
|
|
#
|
|
# Java_JAVA_EXECUTABLE = the full path to the Java runtime
|
|
# Java_JAVAC_EXECUTABLE = the full path to the Java compiler
|
|
# Java_JAVAH_EXECUTABLE = the full path to the Java header generator
|
|
# Java_JAVADOC_EXECUTABLE = the full path to the Java documention generator
|
|
# Java_JAR_EXECUTABLE = the full path to the Java archiver
|
|
# Java_VERSION_STRING = Version of java found, 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)
|
|
#
|
|
#
|
|
#
|
|
# The minimum required version of Java can be specified using the
|
|
# standard CMake syntax, e.g. find_package(Java 1.5)
|
|
#
|
|
# 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
|
|
#
|
|
# For these components the following variables are set:
|
|
#
|
|
# ::
|
|
#
|
|
# Java_FOUND - TRUE if all components are found.
|
|
# Java_INCLUDE_DIRS - Full paths to all include dirs.
|
|
# Java_LIBRARIES - Full paths to all libraries.
|
|
# Java_<component>_FOUND - TRUE if <component> is found.
|
|
#
|
|
#
|
|
#
|
|
# Example Usages:
|
|
#
|
|
# ::
|
|
#
|
|
# find_package(Java)
|
|
# find_package(Java COMPONENTS Runtime)
|
|
# find_package(Java COMPONENTS Development)
