# - 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_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 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) # # 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__FOUND - TRUE if is found. # # Example Usages: # find_package(Java) # find_package(Java COMPONENTS Runtime) # find_package(Java COMPONENTS Development) # #============================================================================= # Copyright 2002-2009 Kitware, Inc. # Copyright 2009-2011 Mathieu Malaterre # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # The HINTS option should only be used for values computed from the system. set(_JAVA_HINTS "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\2.0;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.9;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.8;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.7;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.6;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.5;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.4;JavaHome]/bin" "[HKEY_LOCAL_MACHINE\\SOFTWARE\\JavaSoft\\Java Development Kit\\1.3;JavaHome]/bin" $ENV{JAVA_HOME}/bin ) # Hard-coded guesses should still go in PATHS.
